The first versatile nuclear icebreaker Sibir Project 22220 was officially accepted by the customer at the Baltic Shipyard on December 24. Project 22220 nuclear icebreakers have accumulated the rich experience of shipbuilders and mariners. We believe that the efficient operation of such icebreakers is a key factor to enable the sustainable development of the Northern Sea Route navigation. The commissioning of the first-in-series versatile nuclear icebreaker Sibir will strengthen Atomflot’s position in the ArcticArctica, the flagship versatile nuclear icebreaker, is operating in the Northern Sea Route right now. The nuclear icebreaker is escorting a convoy towards Pevek Port.The flagship icebreaker operation has shown that the vessel is fully compliant with the customer specifications. The RITM 200 reactor with an integrated steam generator has also proved to be highly efficient. The Arctica nuclear icebreaker successfully navigated the shallow waters en route to the Arctica Gate oil terminal in May 2021. It proved her suitability for both open sea and polar river estuary operations.
